Nikko is very sweet and responsive. I didn't have access to a good map of Bangkok while booking. It was too late to cancel when I realized the apartment is actually quite far from main tourist attractions of Bangkok (temples and palace). There are buses and the metro. But you will need to walk for at least 15min to get to most of them. Then it's about an hour in Bangkok traffic! We stayed 2 nights. Overall we enjoyed our stay and Nikko is very accommodating! Thanks!
